I currently have 2 bucks live together happily without any fight. Now I plan to buy some does and breed with one of my bucks. If I seperate one of the bucks and put him with a doe (in another cage that doesn't belongs to any mouse) for breeding for less than 10-15 minutes and then return the mice back to their own group. Will this going to work? Will the bucks start fighting? My two bucks stay together since I bought them and I just don't want to seperate them.
Another question, my bucks are now 8 months old and if I buy some does, I have to wait another 3 months to let them grow. At that time, will they be too old to breed?(both of them never breed before)
